Abstract

This study purpose is to analyze outcomes of modern intramedullary (IM) nails with a locked distal screw versus periarticular locking plates for peri-prosthetic supracondylar femur fractures in TKA. Ninety-five consecutive fractures in 91 patients were retrospectively reviewed. Fixation included 29 knees with a retrograde IM nail and 66 periarticular locked plates. Six patients died and 4 were lost to follow-up. There were 2 (9%) nonunions in the IM nail group and 12 non-unions/delayed-unions (19%) in the locked plate group (P= 0.34). A mean of 5.0 distal screws was used in locked plates versus 3.8 distal screws in the IM nails (P< 0.001). Despite a greater quantity of screws in the distal fragment, the failure rate of locked plating was twice that of IM nail fixation.
